Definitions

  • the present disclosure relates to a covering for underlays of flooring.
  • the aim of the present disclosure is to provide a covering for underlays of under-flooring that is capable of improving the background art in one or more of the above mentioned aspects.
  • the disclosure allows perfect curing and drying of the adhesive present on the lower face of the tiles.
  • the disclosure avoids the occurrence of unsightly effects.
  • the present disclosure overcomes the drawbacks of the background art in a manner that is alternative to any existing solutions.
  • the disclosure further obtains a continuous waterproofing of the underlay.
  • the disclosure also provides a covering that is highly reliable, relatively easy to provide and at competitive costs.
  • a covering for underlays of flooring characterized in that it comprises:
  • FIG. 1 is a perspective view of a membrane of the covering according to the disclosure
  • FIG. 2 is a sectional perspective view of the covering according to the disclosure in a first variation thereof;
  • FIG. 3 is a sectional perspective view of the covering according to the disclosure in a second variation thereof;
  • FIG. 4 is a side view of the joining of two adjacent coverings.
  • FIG. 5 is a side view of the joining of two adjacent coverings.
  • the covering according to the disclosure is adapted to be laid over a slab, or on a flooring suitable for a ceramic or natural stone covering, and to receive the tiles in an upper region.
  • the covering 10 comprises:
  • FIG. 1 shows the membrane 11 . It is made of plastic material, preferably polyethylene or polypropylene, or other polymeric plastic material or, also, other material suitable for thermoforming or molding.
  • the studs 13 have a plan shape mainly with a circular external profile.
  • plan shape can be different: for example, square, triangular or shaped like another regular or irregular polygon.
  • the studs 13 are substantially frustum-like, having a reduction in cross-section away from the base 12 , are hollow inside, and are obtained by thermoforming.
  • the studs 13 may have a frustum-like shape with an inverted extension with respect to the one described above and shown in the figures. In this case the reduction in cross-section occurs near the base 12 .
  • the studs 13 have a shape other than the frustum-like one, which can be regular or not.
  • the dimensions of the diameter can vary, preferably, from 1 mm to 50 mm.
  • the height of the studs 13 and their mutual distance also can vary, preferably, from 1 mm to 50 mm.
  • the number of studs, in a 100-m 2 membrane can vary from a minimum of 100, with a stud diameter of 50 mm and a distance of 50 mm between one stud and the other, to a maximum of 250,000, with a stud diameter of 1 mm and a distance of 1 mm.
  • a preferable example of membrane 11 can have the following characteristics: studs with a height between 3 and 5 mm, diameter comprised between 8 and 12 mm at the base and diameter between 7 and 11 mm at the top, distance between the tops of the studs between 4 and 6 mm and center distance comprised between 12 and 16 mm. With these dimensions, the membrane has a distribution of studs comprised between 5000 and 5300 for each square meter and each raised portion has a surface of about 63 mm 2 . Therefore, the membrane has an upper supporting surface of 0.32 m 2 , i.e., 32% of the total surface.
  • the draining layer 14 is positioned on the top of the studs 13 and is preferably constituted by a geotextile material, adapted to allow the passage of water and vapor, therefore adapted to allow the elimination of humidity, with consequent correct curing of the adhesive.
  • the geotextile material is preferably made of NWF, but as an alternative it may be constituted by draining fabric or other material suitable for the passage of water and vapor.
  • the draining layer 14 is advantageously heat-sealed to the top of the studs 13 , in order to avoid separations that can occur with the use of adhesives, owing to loss of bonding or to aging of the adhesives.
  • the draining layer 14 can be glued, by means of an appropriate and strong adhesive (selected for example from heat-reactive adhesives, two-part epoxy adhesives, bituminous adhesives or others that are capable of gripping the material), to the membrane 11 .
  • an appropriate and strong adhesive selected for example from heat-reactive adhesives, two-part epoxy adhesives, bituminous adhesives or others that are capable of gripping the material
  • the anchoring layer 15 is joined below the membrane 11 and is also heat-sealed to the membrane 11 .
  • the draining layer 15 can be bonded, by means of an appropriate and strong adhesive (selected for example from heat-reactive adhesives, two-part epoxy adhesives, bituminous adhesives or others that are capable of gripping the material), to the membrane 11 .
  • an appropriate and strong adhesive selected for example from heat-reactive adhesives, two-part epoxy adhesives, bituminous adhesives or others that are capable of gripping the material
  • the anchoring layer 15 is breathable and perforated and is made of plastic material, preferably a polypropylene fabric, or the like or other material suitable for the passage of water and vapor.
  • the spun material comprises a fabric made of polypropylene, or similar material that allows both bonding to the support and the flow of the humidity present in the support and the management of vapor pressures.
  • the anchoring layer 15 is applied to the lower surface of the membrane 11 exclusively in contact with the base 12 , thus creating hollow volumes below the studs 13 that allow the passage of humidity present in the support and the management of the vapor pressures.
  • the same figure shows the components of the covering in cross-section in different positions, in order to show them in their superimposed arrangement. In the product, these have substantially the same extension.
  • Vapor may be generated between the membrane 11 and the anchoring layer 15 due to the presence of residual humidity in the underlay (which, if it moved toward the flooring, would cause efflorescence problems).
  • the hollow space serves as a vapor outlet.
  • the same figure also shows a layer of adhesive, designated by 16 , on which is applied the covering 10 .
  • the anchoring layer 15 is joined in a lower region to the membrane 11 , covering substantially all of its lower surface.
  • the anchoring layer 15 follows the shape of the membrane 11 and thus adheres to the cavities of the studs 13 .
  • the figure shows the components of the covering in cross-section in different positions, in order to show them in their superimposed arrangement.
  • the space below the studs 13 is filled with the adhesive 16 , preferably of the cement-based type, increasing the load-bearing capacity with respect to the previous version.
  • a connecting strip 17 preferably made of polyethylene, can be joined to the perimetric region of the membrane 11 , below the anchoring layer 15 , to allow the correct joining of two adjacent coverings 10 and prevent the passage of water, giving the system a waterproofing function.
  • the junction of the two coverings 10 is shown in FIG. 4 and in FIG. 5 , which also show the interposition of a polymeric sealing adhesive 18 used for the junction itself.
  • the strip 17 comprises preferably a flattened membrane made of polyethylene or the like, with two fabrics made of polyethylene or the like anchored on both sides which ensure the anchoring of the adhesive.
  • the strip 17 can be monolithic with the covering 10 . It is partially heat-sealed to the lower face of the covering 10 and partially protrudes from it with a portion. In this case, joining occurs by gluing a second covering 10 to the protruding part of the strip 17 , by means of the sealant 18 .
  • the draining layer facilitates the passage of humidity to the underlying membrane: because of its particular shape, which substantially creates air pockets or chambers that allow humidity to reach the joints between the tiles; or perimetrically along the external edges of the flooring, allowing perfect curing and drying of the adhesive under the tiles.
  • the disclosure achieves the intended aim and advantages, providing a covering that is adapted to allow a perfect curing and drying of the adhesive present on the lower face of tiles, even large ones, avoiding the occurrence of unsightly drying defects.
  • the materials used may be any according to the requirements and the state of the art.
